sera gH-Test FRESH WATER, PONDWATER TESTINGCARE

It simplifies the process of tracking total hardness levels for around 420°dGH. If the GH values are too low, we suggest using sera mineral salt. To decrease high total hardness, mix in R/O water. For producing softer water, consider adding sera blackwater aquatan or filtering through sera super peat.

Directions for use:

  • Shake the reagent bottle thoroughly before use! Avoid letting the water being tested come in contact with aquarium or pond water!
  • 1. Rinse the measurement vial with the water to be tested multiple times, then fill it to the 5 ml mark. Wipe the outside of the vial to dry.
  • 2. Add the reagent drop by drop. Gently shake the vial after each drop, until the color transitions from red to brown and finally to green.
  • 3. The quantity of drops used represents the total hardness (in °dGH). For example, 5 drops equal 5°dGH.
  • 4. Cleaning: Rinse the vial thoroughly with tap water before and after each test. Immediately close the reagent bottle after use. Store it at room temperature and away from light. Keep it locked up and out of children's reach. For testing ornamental fish aquariums and pond water only.

US Information for use

Most ornamental fish come from regions where the soil is low in minerals. However, in many other parts of the world, the opposite is true. Rainwater leaches calcium and magnesium from the soil, resulting in hard water. With the sera gH-Test, you can swiftly assess the precise total hardness. Understanding natural conditions aids in selecting the ideal fish species for a community aquarium and is essential for successful breeding. To reduce high total hardness levels, mix in R/O water. Using a combination of sera aquatan and sera blackwater aquatan or filtering through sera super peat will help achieve soft water, which is necessary for many South American fish (such as those from the Amazon basin).

Colorful, Sturdy & Great Value
Color: Large Set of 4
Purchased for our two puppies when they were 2 months old and weighed about 14 pounds so theses balls were a little big for them to hold in their mouths but that didn't stop them from trying. While they did like these balls they much preferred softer soccer balls, the later of which did not hold up well at all. I had hoped they would play with these balls more when they were older but that hasn't happened 5 months later. I guess it's no fun if you can't tear the toy apart. Colors are very bright and they do enjoy chasing after them as long as I am the one rolling them across the room for them. Maybe when they progress to batting things with their paws they will start to do this for themselves.

3.5, Not 3.0
Color: Medium Set of 6
These balls were almost exactly what I needed. I was replacing my boy’s favorite ball, which is the 3” squeaky, spikey ball that fits in the chuck it launcher. Unfortunately I saw the shiny object next to it and because there were SIX balls and a dollar less, I failed to see that these are 3.5” balls instead of 3”…. Great balls but no fitty in the slingy. Buyer beware. No chuck it no problem. Save a buck.
